FEEDING MECHANISM FOR WOODWORKING MACHINERY.

Application filed December 2, 1912.

To all whom it may concern:

Be it known that I, PETER A. SoLEM, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Feeding Mechanism for W'oodworking hflachinery, of which the following is a specification.

My invention is primarily applicable to the feeding mechanism in a wood-planing machine, located in that part of. the machine in rear of a cutter-head or cutter-heads, and is primarily applicable to what is known in this art as a feed-out roll.

It is of course obvious that the invention may be employed in other relations in a woodworking machine if such should be desired.

It is the object of my invention to provide novel means whereby a feed-roll is normally held out of contact with the stock being fed through the machine and arranged so that the feed-roll may be temporarily brought into contact with said stock; further, to provide novel means for mounting, adjusting and moving the feed-roll support; further, to provide novel means whereby, after the feed-roll has been brought into contact with the stock, such contact is released; further, to provide a novel relation between a shaving chute and the feed-roll and novel means for mounting the shaving chute with relation to the feed-roll support; and the invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure 1 represents a plan View of a wood-planing and matching 0r flooring machine, in which the principal parts of the machine are diagrammatically shown in order to designate a usual location for the main parts of the machine, and also showing my invention applied thereto, the gearing for the latter being removed. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation of an embodiment of my invention as exemplified in a structure of the character shown in Figs. 1 and 2. Fig. 4 is an end elevation of the same partly in vertical cross-section on the line 4-4- of Fig. 3; and, Fig. 5 is a vertical section of the same on the line 5-5 of Fig. 4.

Specification of Letters Patent.

Patented Sept. 1, 1914.

Serial No. 734,518.

11 represents a wood-planing machine of desired character and is instanced as having feed-in rolls 12, 13, and 14, 15. These feedrolls are mounted in suitable manner and rotated by suitable and usual means, not shown because well-known, for feeding the stock, shown at 16, in the direction of the arrow a.

17 represents an upper cutterhead, 18 a lower cutter-head, and 19, 20, side cutterheads. One or more of these cutter-heads may be employed in connection with my invention and the same may be arranged and driven in ordinary or usual manner. Other suitable wood-cutting agency may be employed.

21, 22, represent a pair of feed-rolls which are arranged to act upon the stock after the same has been acted on by the cutter-head or cutter-heads.

It is usual in machines of this character for the stock to be fed upon and lengthwise of a table 24 in the main frame 25 of the machine and to rest upon the lower feedroll or rolls in passing through the machine.

I have shown the feedrolls 21, 22, as driven by power. Thus the feed-roll 22 has a shaft 26 which is journaled in bearings 27 and has a gear 28 secured thereto. The gear 28 is meshed by a gear 29 on a cross-shaft 30, journaled in bearings 31 of the main frame, the cross-shaft also having a gear 32 fast thereon which is meshed by a pinion 33 fast on a shaft journaled in bearings 35 and having a pulley 36 fast thereon driven in suitable manner, as from a pulley 37 mounted on one of the shafts concerned in driving the feed-in rolls.

4-1 is an intermediate gear which meshes with the gear 28 fast on the lower rollshaft 26 and with a gear 42 fast on a cross-shaft 43. The gear 41 is mounted on a stud 44 at the adjacent ends of links 45, 46, the distanced ends of said links being pivoted respectively about the roll-shaft 26 and the cross-shaft 43 for forming expansion-link mechanism between the lower feed-roll shaft and said cross-shaft. The crossshaft 43 is journaled in bearings 47 of a feed-roll frame 48.

51 is a feed-roll housing which has bearings 52 about the cross-shaft 43, the bearings 52 being preferably journaled about the journal-ends 53 of the bearings 47 in which said cross-shaft 13 is journaled.

541 is a gear fast on the cross-shaft 43 and 55 is a gear fast on the roll-shaft 56 of the feed-roll 21, this last-named shaft being journaled in bearings 57 of the housing 51.

58 is a stop on each end of the housing arranged to engage a lug 59 on each of the side slides 60, of the feed-roll frame for limiting the downward movement of the housing and consequently of the feed-roll 21.

61 is a spring located between the feedroll housing and a bracket 2 of the feedroll frame for pressing said upper feed-roll downwardly toward the stock and permitting yield of the same with relation to the stock.

The feed-roll frame is adjustable up and down on the main frame, the side slides 60 being guided by guidcways 63 in the main frame. This adjustment shown accomplished by means of screw-rods ($5, each of which is jonrnaled in a bearing 66 in the feed-roll frame and has threaded connection with a nut 67 pivoted in a bearing 68 in a link 69, provided with a bearing 70 in which an eccentric 71 is journaled. The screw-rod may also be 'crtically nmvable in and guided by bearings 72 at a point adjacent to the nut (37, and pass loosely through openings 73 in the bearing 68, these openings being sufiiciently large to permit the swinging of the link about the nut.

In the fo m shown, the upper end of each of the screw-rods has a worm-wheel 74 fast thereon meshed by a worm 75 on a crossshaft 76 jourualed in bearings 77 of the feed-roll frame and having a hand-wheel 78 thereon, whereby the screw-rods are turned and the feed-roll frame adjusted bodily up and down on the main frame of the machine.

81 is a rock-shaft on which the eccentrics are formed. It is jonrnaled in bearings 82 on the main frame. This rock-shaft has an extension 83 which has a pinion 84 fast thereon, the rocking axis of the pinion and rock-shaft being ci'iincident. The pinion is meshed by a segn'icnt-gear 85, the segment gear being on a lever 86 pivoted on a bolt 87 to the main frame. These parts are shown at the feed-out end of the machine. A link 91 is articulated at to said lever and eX- tends to a suitable part of the machine, as to the feed-in end of the machine, where it is connected to a suitable operating mechanism, shown as a bell-crank structure 93 comprising an arm 91 to which the link is articulated at 95 and a treadle-arm 96, this structure being rockable on a stud 97 located in a bearing 98 on the main frame.

Springs 101 are coiled about the rockshaft 81, one end of ca h of the springs being provided with an eye 102, received about a pin 103 rigid in the main frame, the other end of each of the springs being provided with an eye 10a through which a bolt 105 passes into the rock-shaft. The construction and relation of the parts are such as to nor mall y and automatically cause the eccentrics T1 to be located at their uppermost point of movement for locating the feed-roll 21 in raised position off the stock, and to cause the lever so to contact a stop 106.

110 a pneumatic head, shown in the form of a shaving chute, through which a current of air is caused to pass, preferably in the direction of the arrow 5 for drawing the shavings and slivers from the planed surface 111 of the board. If desired, the current of air may be reversed for blowing the shavings and slivers off the board. The pneumatic head, as shown, comprises the month 112 and the laterally extending crosspieces 113. The head pivoted on trunnions 114 in bearings 11.5 on bearing-blocks 116 secured to the feed-roll frame, as by bolts 117 passing through slots 118 in said block into said frame, permitting adjustment of the pneumatic head up and down on said feed-roll frame. The pneumatic head has a stop 119 at each end thereof arranged to engage a lug 120 on each of the side slides of the feed-roll frame.

The month 112 opens adjacent to the board ainl is provided with a lip 1, which is preferably a slightly flexible re: hent lip, at the rear wall of the said mouth, extending across the width of the board, and acting as a shaving-wiper for the planed surface of the board, and being arranged to make close contact with said planed surface. This wiper is preferably fabric or reiofi'ircral rubber or leather and is arranged to wipe the shavings and slivers off the planed surface of the stock. to prevent them being pressed into said planed surface by the feedout roll, when the latter is in active relation with the stock, and thereby avoid the marking and disfiguring of said planed surface.

125 is a pneun'latic tube with which the pneumatic head has connection and which leads to any suitable suction or blower system. The connection between the pneumatic head and the pneumatic tube is preferably a loose connection to permit ready swinging of the pneumatic head. Thus the head is provided with a neck 126 with which a section 125 of the tube may have loose telescoping connection, as shown at 127, a pin in the neck being received in a slot 129 in said section. The section 125 may have loose sliding telescoping connection with the tube proper, as shown at 130, if desired.

The object of pivoting the pneumatic head is to permit it to yield when the lip 122 is contacted by the stop, this lip, while being resiliently flexible being also preferably sufficiently stifl so as not to be unduly flexed this normal relation being a positioning of the feed-roll with relation to said board, so, that the feed-roll is out of contact with said board. In this relation of the parts, the eccentrics 71 are located in upward position. In this relation of the parts the boards are arranged to feed one another through the machine by end contact by feeding force applied by the feed-in rolls 12, 13 and 14,

15, it being understood that suitable usual guides and pressure devices act on the stock in passing through the machine, these guides and pressure devlces not being shown because well known. When the last board of the series passes beyond the feeding contact of said feed-in rolls, in order to feed the remaining portion of said board through the machine, the operator will manipulate the feed-roll 21, bringing the same into contact with the board, by bearing upon the treadle-arm 96, for drawing the feedroll 21 downwardly, this being accomplished in the present exemplification by the downward movement of the feed-roll frame 48. The operator is enabled to apply great force for acomplishing this movement as he can apply his whole weight upon the treadlearm, and can operate the feed-out roll from his usual position at the feed-in end of the machine. When this movement takes place, the pneumatic head preferably also moves toward the board, so that the flexible lip may form more intimate wiping contact with the planed surface of the end of the board for preventing passage of any shavings or slivers past said lip on the planed surface of the board.

When the end of the board is past the feed-roll 21, the operator releases the treadle-arm whereby the feed-roll 21 is automatically returned to normal position by means of the spring 101.

The feed-roll 21 being automatically returned to normal position out of contact with the stock, and such contact being effected only during manipulation of the contact means by the operator, it is assured that contact of said feed-roll with the planed surface of the stock shall be maintained only during the active manipulation of said contact means by the operator, thereby preventing negligent contact between said feedroll and the planed surface of the board.

The pneumatic head and its wiper are adjustable with the feed-roll toward and.

from the stock, so that when the feed-roll is adjusted, the pneumatic head and its wiper are simultaneously adjusted with it, the pneumatic head being shown mounted on the feed-roll frame.
